hello, first of all apologize for my English (google translator) and to congratulate you all for your great work here exposed.
I am a big fan of this art about a year ago, I tried to take my first steps but I did not get any decent result, but I am determined to keep trying to get something I like.
What I want is to advise me on how to start working because I am completely lost and bundled all the information that I have totally mixed. (I've seen almost all videos gnomonworkshop)

I would like to advise me as if someone were to start from 0, (excluding the management of photoshop) but everything else I want to start from 0.

and if there were any Spanish artist I would also advise would be grateful as it would be easier to understand for any advice, if not use the google each do better xD.

Practice makes perfect.Look into some Photoshop basics tutorials because you never know what you can learn.I would suggest watching tutorials and recreating the same thing to get into force of habit of doing certain techniques.I don't know what your skill level is,but digital matte painting is an advanced technique that requires knowledge of digital painting,photomanipulation and basics of value,scale,depth and perspective.Just keep working and posting your works on internet communities so you can get feedback and criticism about your progress.

ok, thanks for your answer, on the subject of the concepts of scale, depth and perspective, could you recommend me some site or book or something where I can find information.
